In 42 patients with acute unilateral ischemic or hemorrhagic hemispheric stroke, conjugate eye deviation toward the lesioned side was usually of brief duration. It subsided within 48 hours in 24 patients (57%) and lasted no longer than 5 days in 38 patients (90%). Early disappearance of conjugate eye deviation was an isolated phenomenon and preceded any improvement in the other focal neurological deficits, which persisted in their initial severity. In 6 additional patients with stroke, conjugate eye deviation was remarkably prolonged, lasting from 13 to more than 43 days. In all 6 there was evidence for preexisting damage to the contralateral frontal region. Our study suggests that early recovery of conjugate eye deviation in patients with acute hemispheric stroke may be mediated by the contralateral unaffected frontal eye field.
在42例急性单侧缺血性或出血性半球性卒中患者中，双眼向患侧的共轭偏斜通常持续时间较短。24例患者（57%）在48小时内症状消退，38例患者（90%）持续时间不超过5天。共轭偏斜的早期消失是一种孤立现象，且先于其他局灶性神经功能缺损的任何改善，后者仍保持其初始严重程度。另外6例卒中患者的共轭偏斜明显延长，持续时间从13天至超过43天。所有6例均有对侧额叶区域先前存在损伤的证据。我们的研究表明，急性半球性卒中患者共轭偏斜的早期恢复可能由对侧未受影响的额叶眼区介导。
